Delia Busby (Kate Lamb)

In period drama Call the Midwife, Delia is a nurse and midwife who first appeared in season 4 episode 2 when regular character Patsy revealed they were in a long term relationship. Due to negative feelings toward homosexuality in the 1960s, Patsy and Delia were forced to keep their feelings for each other a secret, but they eventually decided to move in together.

Just after they moved, Delia was involved in a traffic accident in the season four finale, leaving her with amnesia and no memory of Patsy. Delia’s mother took her home to Wales, leaving a heartbroken Patsy in London.

They met again a few months later after Delia got her memories back and moved in together again. At the end of season five, they went to a bar tolerant of gay couples after Delia convinced Patsy that it would be nice to know “others like them”.

In season six, Patsy received a letter from Hong Kong telling her that her father was dying, left to be with him and wasn’t seen again until the season finale, while Delia remained behind and spent most of the season pining after her. Delia and Patsy were reunited in the finale and finally got their first on-screen kiss.

Call the Midwife was renewed for seasons 7, 8 and 9 with a Christmas Special included in each. Emerald Fennell and Kate Lamb announced they would not return to the show.
